Fall Tree Pruning in Northern Virginia: What to Prune Now (and What to Leave Alone)
The leaves are coming down across Northern Virginia, and that means one thing for tree care: pruning season is here. Once trees drop their leaves and head into dormancy, it's one of the best times of the year to prune many of them. But not every tree and shrub should be cut back this time of year.
Here's what you can (and should) prune this fall and winter, what's better left until spring, and why now is the time to get on the schedule.
Why late fall and winter are prime pruning season
When deciduous trees go dormant after leaf drop, they stop putting energy into growth. That makes pruning less stressful for the tree. There are other advantages too:
You can see the whole structure. Without leaves, it's easy to spot dead wood, crossing branches, weak branch unions and limbs growing toward your roof.
Fewer pests and diseases are active. Many insects and fungi that spread through fresh pruning cuts are inactive in cold weather.
It's storm prep. Removing dead and weak limbs now means less for winter storms, ice and snow to bring down on your house, car or driveway.
Your yard is protected. Firm or frozen ground holds up better under equipment, and there are no flower beds in full bloom to work around.
What you should prune this fall and winter
Dead, broken and hazardous branches
These come first, any time of year. Dead or cracked limbs can fall without warning, especially under the weight of ice and snow. If they're hanging over your home, driveway, play areas or power lines, have them removed before winter storms arrive.
Oaks
Oaks are one of the best trees to prune right now. Oak wilt is spread by beetles drawn to fresh pruning wounds during the growing season, so Virginia Cooperative Extension guidance recommends pruning oaks in November and December and avoiding oak pruning from March through August.
Most deciduous shade trees, once they're dormant
After the leaves drop, maples, tulip poplars, elms, lindens, sycamores and most other shade trees can be structurally pruned, thinned and raised. Maples and birches may "bleed" sap if they're cut in late winter, which looks alarming but doesn't harm the tree.
Limbs over your roof and structures
Branches rubbing on roofs, siding and gutters cause damage and give squirrels a highway into your attic. Clearance pruning is ideal in the dormant season.
Young trees that need structure
Light structural pruning on young trees helps them develop a strong central trunk and well-spaced branches. It's much easier and less expensive to shape a young tree now than to fix a structural problem in a mature one later.
What to wait on
Spring-flowering trees and shrubs. Dogwoods, redbuds, flowering cherries, crabapples, magnolias, azaleas and forsythia have already set next spring's flower buds. Prune them now and you'll cut off the blooms. Wait until right after they flower.
Trees that are still in full leaf. Pruning a tree hard before it has gone dormant can encourage tender new growth that's easily damaged by the first freeze. Wait until the leaves have dropped.
Heavy shaping of evergreen shrubs late in the season. Light tidying is fine, but major cuts on boxwood, holly and similar shrubs are better done in late winter or early spring.
Topping, ever. Cutting the top off a tree creates weak, fast-growing sprouts and invites decay. Size can be reduced safely with proper crown reduction cuts instead.
Get on the schedule before winter
Dormant season is our busiest time of year for pruning, and the best time slots fill quickly. Booking now gets your trees taken care of before winter storms test them, and you'll head into spring with healthier, safer trees.
Frequently asked questions
Can you prune trees in the fall?
Yes. Once deciduous trees drop their leaves and go dormant, late fall and winter are excellent times to prune most of them. Dead and hazardous branches can be removed any time of year.
What trees should not be pruned in the fall?
Spring-flowering trees and shrubs such as dogwoods, redbuds, cherries, magnolias and azaleas should wait until right after they bloom, or you'll remove next spring's flowers.
Is fall a good time to prune oak trees in Virginia?
Yes. Virginia Cooperative Extension guidance recommends pruning oaks in November and December, and avoiding oak pruning from March through August to reduce the risk of oak wilt.
Why prune trees before winter?
Removing dead, weak and overhanging limbs before winter reduces the chance that ice, snow and wind will bring them down on your home, cars or power lines.
